Two Santa Cruz police officers were killed in a shootout Tuesday afternoon and a suspect who investigators believe killed the officers was chased down and fatally shot minutes later by law enforcement.

"This is a horrific day. We lost two exceptionally fine officers today," Santa Cruz Police Chief Kevin Vogel said at a joint press conference with Santa Cruz County Sheriff Phil Wowak Tuesday evening.

"It's a horrible, horrible day for Santa Cruz," Vogel said.

The Santa Cruz Police Department has never lost an officer in the line of duty.

The officers were shot while investigating a sexual assault case at a house on North Branciforte Drive near Doyle Street at 3:30 p.m.

A second shooting erupted on Doyle Street at 4 p.m. when law enforcement officers unleashed a hail of bullets on the suspected shooter. The suspect was killed.

Multiple law enforcement agencies, including the FBI and SWAT teams, launched a manhunt to look for possible additional suspects, however investigators determined that the gunman acted alone.

"Out of respect for the families, neither of the deceased Santa Cruz City Police Officers will be identified at this time," Sheriff's Deputy April Skalland said.

"The suspect's name will not be released until their identity can be positively confirmed," she added.

A "be on the lookout" was issued by 911 emergency dispatchers immediately after the officers were killed for Jeremy Peter Goulet. It was not clear if Goulet was connected to the shootout, however.

Goulet, 35, of Santa Cruz, was arrested on Feb. 22 at 801 North Branciforte Dr. for disorderly conduct and has a history of sex crimes. Goulet served more than a year in jail in Oregon after he was convicted of spying on young women and videotaping them.

Also during the manhunt, Midtown Montessori and Branciforte School were placed on lockdown. Sheriff's deputies from Monterey and Santa Clara counties were called in to help reunite children with their parents.

Wowak said he will give a second press conference at 9:30 p.m. Tuesday to release more information to the media. Check back with KSBW.com for updates.

Goulet was a former U.S. Army soldier. In 2006, Goulet was accused of raping a female officer shortly after arriving at a base in Hawaii. Goulet was confined to the Army base, where, several months later, he allegedly raped a second female officer.

Two Army court martials brought against Goulet were dropped in exchange for a less than honorable discharge from the military.

Army court-martial could have locked Goulet in prison for the rest of his life. Instead, he was discharged in early 2007.

Santa Cruz Police Chief Kevin Vogel held a joint press conference with Sheriff Phil Wowak just hours after the detectives were slain on Feb. 26, 2013 to let the public know that the gunman was dead.

"This is a horrific day. We lost two exceptionally fine officers today," Santa Cruz Police Chief Kevin Vogel said at a joint press conference with Sheriff Phil Wowak just hours after the detectives were slain Feb. 26, 2013.

Sheriff's deputies were supposed to take over the perimeter and manhunt for Goulet because two SCPD officers had just been killed. But Wowak said SCPD officers refused to leave their posts because they wanted to find the person who had just killed their colleague.

Wowak credited the SCPD officers who refused to leave with catching the suspected gunman before he escaped the area.
